Triggered Sequence HE NDPA HE NDP Trigger UL trigger-based PPDU CSI From HE STAs Trigger UL trigger-based PPDU CSI From HE STAs SIFS 2. Feedback Types: a. SU-type Feedback over full BW b. MU-type Feedback over full BW c. SU-Type Feedback over partial BW (Multiple 26-RUs) for DLOFDMA SU Beamforming d. MU-Type Feedback over partial BW (Multiple 26-RUs) for DL-MUMIMO Beamforming in one RU in case of DL-OFDMA e. CQI-only feedback To assist DL-OFDMA RU allocation SIFS SIFS SIFS SIFS 0..N times Submission Slide 11 Hongyuan Zhang, et. al. (Marvell)
3/5/2025 doc.: IEEE 802.11-16/1133r1 Discussions It is desirable to reduce number of sounding modes, especially the mandatory modes. Non-Triggered Sounding Sequence is preferred to be solely used for SU-Type feedback over full BW. Matching the 11ac implementation. Triggered Sounding Sequence is preferred to be used for MU-Type feedback over full BW. Giving more time to prepare the more complicated MU-Type feedback. Submission Slide 12 Hongyuan Zhang, et. al. (Marvell)
3/5/2025 doc.: IEEE 802.11-16/1133r1 Proposed 11ax Sounding Modes and M/O Non-Triggered Sequence: (Mandatory for beamformee) SU-type Feedback for the Full-BW. (No support for beamformee) MU-type Feedback, CQI Feedback, SU-type partial BW Feedback. Triggered Sequence: (Mandatory for beamformee) MU-type Feedback over the full BW (Optional for beamformee) SU-Type Feedback over partial BW (Multiple 26-RUs) (Optional for beamformee) MU-Type Feedback over partial BW (Multiple 26-RUs) (Optional for beamformee) CQI-only feedback with any start & end 26-RUs Submission Slide 13 Hongyuan Zhang, et. al. (Marvell)
3/5/2025 doc.: IEEE 802.11-16/1133r1 Proposed 11ax Sounding Feedback Types For Triggered sounding sequence: AP sets the feedback type in NDPA, which means that each triggered STA needs to implement all possible feedback options. This makes STA sounding feedback implementation very complicated. The following capability bits are proposed to reduce STA feedback options for Triggered Sounding Sequence : 1 bit for SU-Type Feedback over partial BW with any start & end 26-RUs 1 bit for MU-Type feedback over partial BW with any start & end 26-Rus 1 bit for CQI-only feedback with any start & end 26-RUs Submission Slide 14 Hongyuan Zhang, et. al.
